Abstract
Zero-kinetic-energy (ZEKE) photoelectron spectroscopy was used to probe the vibrational levels in the ground electronic state of the chlorobenzene cation using a two-color photoionization scheme via the $S_{1}$ electronic state of the $neutral^{a}$. Exciting through different $S_{1}$ vibrational levels has revealed mixing of some $S_{1}$ normal coordinates in the ground state of the cation. A previously-identified Fermi resonance in the $S_{1}$ state of the neutral is also confirmed by the ZEKE spectra. The adiabatic ionization energy is measured as $73170 \pm 5 cm^{-1}$.
